    by this action Possible Solutions The warning comes because you have NaN Not a Number in your data somewhere NaN is missing data data points you do not have values for Sometimes this will happen with certain preprocessing but the most likely cause is that when you imported your data it had some missing data points The implication of the warning is that to build a model the algorithm requires values for all variables and samples To handle this problem PLS Toolbox uses a data imputation algorithm which looks to replace missing data by estimating a value for the missing data points building a PCA model of all the data and then using that model to replace the missing data points again this is then repeated until the replaced values converge on unchanging values This procedure is not perfect and can still lead to samples which have high leverage or residuals i e samples that are outliers but if you have lots of missing data it may be the only reasonable approach If data is missing in only a couple of samples you could exclude those samples build a model from the remaining data You can also later use the

    conflict here http www eigenvector com evriblog p 10 However in most versions of the MW Statistics Toolbox boxplot is the only function which uses the MW dataset object unlike the 65 75 of PLS Toolbox functions which use EVRI s DataSet object This means that moving the MW dataset object to the top of the path would break MOST of EVRI s code but moving EVRI s to the top of the path would only break that one function and unfortunately any user code which used their dataset We strive to make the two DataSet objects as compatible as possible but there are some features of the MW dataset object which we either did not think were prudent to include or that were too invasive to the workings of our existing object The result is that the two objects are NOT compatible With no other recourse EVRI decided to make our own boxplot function to reproduce and overload the Statistics Toolbox function Our boxplot covers a reasonable portion of the functionality provided by the Mathwork s boxplot but not all of it If there are any key behaviors you notice it missing let us know and we ll add
